Sustainable development is a philosophy of resource consumption that believes that it is best to conserve and preserve for future generations while at the same time meeting current human needs. This term was first used in the United Nation’s Brundtland Commission in 1983 that was chaired Gro Harlem Brundtland, the Prime Minister of Norway. Sustainable development is also concerned with the human degradation of natural systems and the relationship of this process to the future social and economic challenges facing humans. Research in sustainable development has expanded greatly since the Brundtland Commission.Further, many governments and private companies now apply the principles of sustainable development to their bottom line.
The BEES (Building for Environmental and Economic Sustainability) model provides a powerful technique for selecting cost-effective, environmentally-preferable building...
OverfishingLast Updated on 2014-12-07 17:22:32Overfishing is the human act of extracting aquatic (that is, marine and freshwater) fauna from natural water bodies at a rate greater than the reproductive and recruitment functions can replace that extraction. While there is some evidence that localized overfishing may have occurred in prehistoric eras, the bulk of overfishing has taken place in the last 150 years as the human population has expanded greatly and fishing technologies have enabled harvesting of many species at rates not imagined in earlier times. For over a century man's role in the depletion of certain regional fisheries has been noted. A functional definition of overfishing is sometimes given as the reduction in catch per unit effort by fishermen. Typically the concept of overfishing is linked to an individual aquatic species, and this issue is most often discussed within a specific marine or lacustrine province... More »
Wind turbine bird mortalityLast Updated on 2014-11-30 21:32:32Wind turbine bird mortality is a by-product of large scale wind farms, which are increasingly promoted as an alternative to fossil fuel derived energy production. To adequately assess the extent of impact to avian populations, deeper factors than gross mortality by turbine action must be assessed. In particular, one must examine: (a) impacts to threatened bird species, (b) total impacts due to avian habitat loss as well as direct mechanical kill, (c) ecological impacts due to apex predator bird loss and (d) future siting decisions for windfarms, since much of the prior bird mortality is due to poor siting decisions.
Bird mortality from wind turbines is a significant adverse ecological impact, and threatens to expand in scope dramatically with the rush to develop new energy sources. This impact is measured as high due to the loss of threatened species and due to... More »
International Food Security Assessment: 2012-22Last Updated on 2014-10-26 16:56:26
Food security is estimated to improve slightly in 2012 as the number of food-insecure people in the 76 countries covered in this report declines from 814 million in 2011 to 802 million in 2012. The share of the population that is food insecure remains at 24 percent. Over the next decade, the share of the population that is food insecure is projected to decline from 24 percent in 2012 to 21 percent in 2022, but the number of food insecure people is projected to increase by 37 million. Regionally, food insecurity is projected to remain most severe in Sub-Saharan Africa. Food-insecure people are defined as those consuming less than the nutritional target of roughly 2,100 calories per day per person.
The U.S. Department of Agriculture's Economic Research Service (ERS) has, since the late 1970s, reported annually on food security in a number of developing countries. A key... More »
Sustainable Society IndexLast Updated on 2014-07-31 13:15:01
When we were looking for a suitable yardstick to measure the level of sustainability of a country a suitable instrument could not be found. Although the main existing indexes were examined we had to conclude that none of them seem to fit our needs completely. The main shortcomings are a limited definition of sustainability, a lack of transparency or high complexity and an absence of regular updates. For this reason, a new index – the Sustainable Society Index (SSI) – has been developed. The SSI integrates the most important aspects of sustainability and quality of life of a national society in a simple and transparent way. Consisting of only 22 indicators, grouped into 5 categories, it is based upon the definition of the Brundtland Commission, extended to the Brundtland+ definition by explicitly including the social aspects of human life.

Food Biodiversity Challenges From a Global PerspectiveLast Updated on 2014-07-25 14:03:15
Food collection or gathering has been an important part of human endeavors towards establishing civilization across the long history of human evolution. Humans have demonstrated their ingenuity in identifying and locating new and novel food sources located in their immediate surrounding and during their migration across the planet. Humans have become more successful than other species because of their better foraging abilities and coordinated group work in identifying and locating novel food sources over time. This trial and error approach has enabled humans over time to identify suitable food sources from their local environments. Over time, humans have identified more species that are edible or could be made edible using primitive to modern day recipes and cooking techniques. These long years of trial and errors have generated a wide range of food sources for... More »
